INTRODUCTION

This application is directed at least in part to embodiments of an electronic device (sometimes referred to as a human machine interface) that is mounted in and to a frame of a bicycle, such as an electric bicycle, and used to monitor operations or properties of the bicycle or one or more components associated with the bicycle. The electronic device can, for example, be mounted in a top tube of the bicycle and have an aesthetically clean appearance. The electronic device may be able to integrate and communicate with a variety of components including sensors to facilitate customization of monitoring by the electronic device. The electronic device moreover can be relatively inexpensive, and any connectors of electronic device can be designed to be protected against environmental conditions, such as water, when the electronic device are mounted to the bicycle.

The electronic device can desirably have a relatively minimalist design. The electronic device, in some embodiments, may include a display that does not present alphanumeric characters to an operator. The display can include multiple indicators that individually or in combination present information to the operator, such as the level of charge of one or more batteries or an operating mode of the electronic device or bicycle. The multiple indicators can, for example, include multiple light emitting diodes (LEDs). In some implementations, the display may not include a liquid-crystal display (LCD) like a thin-film-transistor (TFT) LCD. The electronic device can include one or two user input elements, such as buttons, for the operator to directly provide user inputs (for instance, an on/off input to activate or deactivate the bicycle or a mode change input for adjusting a mode of the electronic device or bicycle) to the electronic device. In some implementations, the electronic device may not include more than two user input elements for the operator to directly provide user inputs to the electronic device.

The electronic device can, in certain embodiments, include one connector for receiving data and power from the bicycle or one or more components associated with the bicycle. The electronic device can additionally include another connector for receiving inputs from a remote control device like a handle bar mounted control device. The remote control device can include one or more switches and may connect a data wire to ground when a corresponding one of the switches is pressed. In some implementations, the remote control device may not include any transistors or intelligent components, such as a microprocessor. The electronic device can also include a diagnostic port for servicing or diagnosing any issues with electronic device. The diagnostic port may be hidden when the electronic device is mounted to the bicycle, and the electronic device can include a cover, such as a rubber seal, over the diagnostic port to protect against water entering the diagnostic port when not in use. Further, the electronic device can include a wireless communication interface for wirelessly communicating with other devices and may transmit information such as speed, battery charge, or selected mode using one or more protocols, like ANT+™ or Bluetooth™. The diagnostic port or wireless interface communications can be used to tune, diagnose, or update the electronic device, bicycle, or one or more other components assisted with the bicycle, as well as collect and remotely store data gathered by the electronic device.

The electronic device can have a housing configured to be at least partly mounted in a top tube of a bicycle. The housing can be secured to the top tube by bolting the housing to the top tube on one side of the housing and securing another side of the housing with the spring from inside the top tube. This design desirably, in certain embodiments, can facilitate quick and easy drop in and mounting of the housing to the top tube with the use of no more than one fastener, such as a bolt or screw, that passes through a hole in the housing. In addition, this design advantageously, in certain embodiments, can allow for a large tolerance in top tube wall thickness and shape, as well as a length and width of the cutout for the electronic device in the top tube. The housing can further include a perimeter lip to cover a gap between the electronic device in the top tube. The lip can, for instance, be composed of rubber or plastic. The electronic device can moreover be designed so that any connectors or cables extending from the electronic device are positioned within the top tube when the electronic devices mounted to the top tube.

The electronic device can be set to a mode in which the display presents for a period of time (such as a 2, 3, 5, or 10 seconds) certain information in response to a user input, but otherwise does not present the certain information. This mode can be termed a dark mode and may be set according to instructions received from another device, such as instructions provided by an application running on a smart phone.

The electronic device can include a display that presents a state of charge of one or more batteries in percentage increments (such as 5%, 10%, or 20% increments). Each percentage increment can be denoted by a separate indicator, and activation of one or more indicators can denote a state of charge that at least meets a threshold level corresponding to the activated indicators. The display can further simultaneously present the state of charge of two batteries. The state of charge of one of the two batteries can be presented in a different color from the state of charge of the other of the two batteries. In addition, the state of charge of one of the two batteries can be overlaid on the other of the two batteries such that the battery having the lower state of charge is shown on top. When the state of charge of both of the two batteries may be below a threshold level, a single combined indicator can be used to represent a dual low battery condition.

The electronic device can continuously monitor the bicycle and one or more components associated with the bicycle when the bicycle is in operation. If any errors occur during operation, the electronic device can store a snapshot associated with the error so that the snapshot can be later used for analysis or troubleshooting. The electronic device can also record in log files gathered bike-related data, such as speed, cadence, location, selected mode, or motor temperature. The log files can then be used to analyze rides or provide the bike-related data to platforms, such as social platforms like STRAVA™. In some implementations, the record function can be switched off by default and may be activated by an operator before being initiated. Advantageously, in certain embodiments, one or more of these features of the electronic device can obviate the need for bringing a smart phone when riding the bicycle because the electronic device can automatically and easily handle gathering of data about rides.

The electronic device can be reset in some instances without utilizing a separate tool, such as an application, diagnostic, or other communication with another device. The electronic device can, for example, be reset by an operator holding one of the user input elements for a period of time (for example, 2, 3, 5, or 10 seconds) during startup of the electronic device. The reset can desirably reset system parameters, such as those parameters that may be adjusted by an operator, and may be useful in instances like transferring of the electronic device or bicycle to another operator.

The electronic device can also facilitate the addition of one or more lights to the bicycle. An in-line Y splitter can be connected to a connector of the electronic device, which may route one or more voltage and ground lines for the one or more lights.

FIG. 2A illustrates a top perspective view of the electronic device 112 of FIG. 1A. The electronic device 112 includes a housing that has an upper portion 201 and a lower portion 202. When the electronic device 112 is mounted to the bicycle, the lower portion 202 can be positioned within the frame 110 and the upper portion 201 can be positioned above the frame 110 and visible when viewing an outer surface of the bicycle 100. The upper portion 201 can include a downward sloping portion 203 and an inwardly sloping portion 204. The upper portion 201 may include a hole 206 usable for securing the upper portion 201 to the frame 110 with a fastener like a bolt or screw.

The lower portion 202 can include a spring 208 configured to press against an inner surface of the frame 110 to secure the electronic device 112 to the top tube. The spring 208 can, for example, be a plate spring. The lower portion 202 can additionally include a connector 210. The connector 210 can be an analog connector and may include a first cable 212 (such as a HIGO 6-pole female cable) and a second cable 214 (such as a HIGO 5-pole male cable) for receiving data or power from or transmitting data or power to the bicycle 100 or one or more other components associated with the bicycle.

The upper portion 201 can include a first user interface element 220 and a second user interface element 222. The first user interface element 220 can, for example, be used to receive a user input to activate or deactivate the bicycle 100, such as a motor of the bicycle 100 or one or more components associated with the bicycle 100. The second user interface element 222 can, for instance, be used to receive a user input to switch modes for the bicycle 100 or one or more other components associated with the bicycle 100.

The upper portion 201 can further include a first display area 230 and a second display area 232. The first display area 230 can be used to display a level of charge of one or more batteries associated with (for example, supported by) the bicycle 100, such as is described in greater detail with respect to FIG. 6. The second display area 232 can be used to indicate whether the electronic device 112 or the bicycle 100 is activated or to identify a mode of operation for the electronic device 112 or the bicycle 100.

FIG. 2B illustrates a bottom perspective view of the electronic device 112 of FIG. 1A. The lower portion 202 can include a speaker 240, such as a beeper, for outputting information audibly to an operator.

As can be seen from FIG. 2C, the spring 208 can include a point 209 that is configured to contact and apply force against the inner surface of the frame 110 to secure the electronic device 112 to the frame 110. The electronic device 112 can include a diagnostic port positioned behind a cover 250 as shown in FIGS. 2C and 2D. The diagnostic port can be used to service and perform diagnostics on electronic device 112, the bicycle 100, or one or more components associated with the bicycle 100. In one implementation, the diagnostic port can be a Universal Serial Bus (USB) port.

FIG. 3A illustrates an environment 300 in which the electronic device 112 of FIG. 1A may communicate with other devices. As shown, the electronic device 112 can communicate via a medium, such as a Controller Area Network (CAN bus) or other channel, with a torque sensor 310, a motor controller 312, one or more batteries 314, and one or more additional components 316. The electronic device 112 can additionally communicate via wired or wireless communications with the remote control device 130, a personal computer 320, a smart phone 322, and a display 324.

The electronic device 112 can receive a torque signal from the torque sensor 310 that is indicative of a torque at the rear axle 120 or another part of the bicycle 100. The electronic device 112 may communicate with the motor controller 312 so that the electronic device 112 can monitor operations or properties of the motor controller 312 or provide control commands to adjust operations by the motor controller 312. The electronic device 112 can receive one or more batteries signals from the one or more batteries 314 that is indicative of a level of charge of the one or more batteries 314. For instance, the one or more batteries 314 can include two batteries, and the electronic device can receive one battery signal from each of the two batteries to determine the level of charge of the individual batteries.

FIG. 3B illustrates an example components of the electronic device 112 of FIG. 1A. The electronic device 112 can include a processor 330, a memory device 332, a user interface 334, a communication interface 336, and a Global Positioning System (GPS) antenna 338. The processor 330 can control operations of the electronic device 112 according to executable instructions stored in the memory device 332. The processor 330 may also store gathered bike data to the memory device 332. The user interface 334 can receive user inputs from an operator, such as via selection of the first user interface element 220 and the second user interface element 222 by the operator. The communication interface 336 can facilitate wired or wireless communications between the electronic device 112 and other devices. The GPS antenna 338 can provide a location of the electronic device 112, such as geographical coordinates corresponding to the location of the electronic device 112 over time.

FIGS. 4A and 4B illustrate perspective views of the remote control device 130. The remote control device 130 can be attached to the handle bars of the bicycle 100 by positioning and securing the handle bars in the hole 410. The remote control device 130 can include multiple remote user interface elements, including a first remote user interface element 420, a second remote user interface element 422, and a third remote user interface element 424 for receiving user inputs to control operations of the electronic device 112. The remote control device 130 can transmit control signals to the electronic device 112 via a connector 430 of the remote control device 130. Each of the first remote user interface element 420, the second remote user interface element 422, and the third remote user interface element 42 can, for instance, include a switch that connects a different data wire to ground when the switch is pressed. In some implementations, the remote control device 130 may not include any transistors or intelligent components, such as a microprocessor. As can be seen from the tear down of the remote control device 130 in FIG. 4B, the remote control device 130 can include a top housing 440, rubber keys 442, internal plugs 444, flexible printed circuits (FPCs) with clickers 446, a bottom housing 448, a seal plug 450, a nut plate 452, a screw 454, a bushing 456, and a cable 458.

FIG. 5 illustrates a configuration 500 for connecting one or more lights to the electronic device 112 of FIG. 1A. The first cable 212 can be connected to a Y splitter 510. The ends 512 of the Y splitter 510 can be connected to the one or more lights and provide voltage and ground wires for the one or more lights.

FIG. 6 illustrates battery status displays 600 by the electronic device 112 of FIG. 1A. The battery status displays 600 in particular can be presented in the first display area 230 shown in FIG. 2A.

The Battery 1 State of Charge Percentage (SOC %) row and the Battery 2 SOC % row indicate the state of charge (sometimes referred to as a level of charge) of battery 1 and battery 2 over times 1-9 as numerical percentages. For example, at times 3, 7, and 9, battery 1 can respectively have a state of charge of 100%, 20%, and 7%, and at times 3, 7, and 9, battery 2 can respectively have a state of charge of 100%, 100%, and 5%.

The 1-10 rows indicate the state of charge of the two batteries in the form of activated, colored indicators (such as LEDs) that correspond to the numerical percentages listed in the corresponding time column. Notably, a presented scale for battery 1 may be different from the presented scale for battery 2 (for instance, 100% state of charge for battery 1 can be indicated by activating all 1-10 of the indicators so each indicator represents an around 10% increase in charge while 100% state of charge for battery 2 can be indicated by activating all 1-5 of the bottom indicators so that each indicator represents an around 20% increase in charge). Moreover, the indicators for battery 1 can be presented in a different color from the indicators for battery 2. In one example, at time 3, all 1-10 of the blue indicators can be activated corresponding to the 100% state of charge for battery 1, and all 1-5 of the green indicators can be activated corresponding to the 100% state of charge for battery 2. In another example, at time 7, 1 and 2 of the blue indicators can be activated corresponding to the 20% state of charge for battery 1, and all 1-5 of the green indicators can be activated corresponding to the 100% state of charge for battery 2. In yet another example, at time 9, a single combined red indicator can be presented indicating that both batteries are below threshold levels, such as a 10% state of charge.

Accordingly, at time 1, the first display area 230 can appear as shown in box 602. At time 2, the first display area 230 can appear as shown in box 604. At time 3, the first display area 230 can appear as shown in box 606. At time 4, the first display area 230 can appear as shown in box 608. At time 5, the first display area 230 can appear as shown in box 610. At time 6, the first display area 230 can appear as shown in box 612. At time 7, the first display area 230 can appear as shown in box 614. At time 8, the first display area 230 can appear as shown in box 616. At time 9, the first display area 230 can appear as shown in box 618.

The first display area 230 can simultaneously present the state of charges of battery 1 and battery 2 so that the state of charge of one of battery 1 or battery 2 is overlaid on the state of charge of the other of battery 1 or battery 2. The first display area 230 can moreover present the state of charges of battery 1 and battery 2 such that the battery having the lower state of charge is shown overlaid on top. In other embodiments, the battery having the higher state of charge may instead by shown overlaid on top. Moreover, the state of charge of one of battery 1 or battery 2 may be presented with a smaller width than the state of charge of the other of battery 1 or battery 2 (for example, as illustrated where the state of charge of battery 1 has a smaller width than the state of charge of battery 2).
